The flamethrower was finally successfully tested, unlike other nobles who cheered loudly, but Li Tai came to the side of the flamethrower after Jia Yi extinguished the flame on the flamethrower, carefully checked what was the difference between Jia Yi's flamethrower and the previous flamethrower, and finally summarized it until he thoroughly understood the working principle of this flamethrower.

"Jia Yi, in fact, you have already figured out how to make a perfect flamethrower, right?"

In the face of Li Tai's questioning, Jia Yi was a little speechless, he was still a random assembly full of accidents before, just entered the palace once, and after coming back, it became very perfect, and even Li Tai, who had learned how to pick potential safety hazards from Jia Yi's body, failed to find any problems on this flamethrower, and entered the palace once? This is obviously not the answer to the question, so the real answer is that Jia Yi has long known the correct way to make a flamethrower, and before that he was just leading everyone through experiments that would appear in various situations.

In the face of Jia Yi's speechlessness, Li Tai's face that was still very serious before was replaced by a smiling face when the ice and snow melted, and he reached out and patted Jia Yi's shoulder and said: "I know you want us to increase our experience and let us know that it takes great effort for anything to appear, although I was slightly injured in the previous experiment, but I don't blame you." ”

The emergence of any knowledge requires countless accumulation and verification, although Jia Yi's idea is far less noble, but Li Tai's brain supplement puts him in such a position, since Li Tai has said it, then we are such noble people, the back that has just bent down is instantly straight, as if he is really as Li Tai said, completely for the good of everyone.

For Cheng Chumo, who was a little bit less brainy, Sun Chong and the others scratched their heads after hearing Li Tai's words, and finally couldn't figure out why Jia Yi didn't directly take out the flamethrower at the beginning, but let them test it again and again.

When they asked the doubts in their hearts, the smile on Jia's face suddenly disappeared, and he coughed lightly and said in a low voice: "The success of the flamethrower just now was purely accidental, we still have to conduct a few experiments, Changsun Chong, Cheng Chumo, this time there are two of you to carry it out." ”

As soon as they heard this, Cheng Chumo and Changsun Chong immediately opened a safe distance of more than ten zhang from Jia Yi.

The flamethrower was successfully manufactured, and the rest was the assembly of the hot air balloon, which was not too difficult, and with the concerted efforts of everyone, the hot air balloon was soon lying flat on the ground, and all kinds of ropes connected the ball and the basket tightly, without any possibility of falling.

After a long period of research and development, the hot air balloon has finally been successfully completed, and if the first lift-off experiment is carried out, it is definitely a big thing, and it must not be completed hastily, and it must be picked a good day and an auspicious day, and the incense must be burned and sacrificed to the sky.

As the emperor's favorite son, Li Tai can always find the figure of a Taoist priest by his side, a little Taoist priest saw Li Tai's eager expression on his face, his eyes rolled quickly, and then pretended to reach out and pinch it, and his face bloomed with a happy expression.

"King Qiqi Wei, tomorrow is a good day and an auspicious day."

The little Taoist's words made Li Tai very happy, and after rewarding the little Taoist with ten yuan in his hand, he came to Jia Yi's side and told Jia Yi the results of the calculation.

Hearing this, Jia Yi looked up at the sky, walked to the side of the little Taoist, and said softly: "You go to Yuan Tiangang now, let him hurry up and make a good day, tomorrow is definitely not a good day, at least the weather will not be too good, don't say that I won't help you, there will be rain all day tomorrow, if His Royal Highness King Wei gets angry and takes your Daomen to open the knife, don't blame me for not reminding you today." ”

A simple look at the weather Jia Yi will still be, although there is no guarantee that there will be rain 100% tomorrow, but looking at the sunset and the clouds in the sky, Jia Yi can calculate that tomorrow's weather will not be too good, hot air balloon is the aviation equipment that needs good weather the most, if it catches up with the rain, if you want to take off, it is simply a fool's dream.

The little Taoist priest was shocked when he heard Jia Yi's words, although he didn't know whether what Jia Yi said was true or not, but he didn't dare to joke about the future of Daomen, he knew that his words had already been said, and there was absolutely no reason to take it back, and now he could only go to Yuan Tiangang for help according to what Jia Yi said.

How else to say that it is a big fool, when the sky is about to darken, Yuan Tiangang finally came to Jia's Manor before Li Tai returned to the palace, first saluted Li Tai, then pretended to make a calculation, and then smiled and bowed to Li Tai and said: "Tomorrow is indeed a good day and auspicious day, but things do not fulfill people's wishes, tomorrow the Dragon King of the East China Sea will go to Beihai to celebrate the birthday of the Dragon King of the North Sea, the wind from the tiger, the rain from the dragon, the place where the Dragon King passes will inevitably rain heavily, it is a good day tomorrow but it is disturbed by the Dragon King, However, Lao Dao has just recalculated, three days later is a better day, it just so happens that His Royal Highness King Wei should have a lot of things to prepare, how about putting the day after tomorrow the day after the hot air balloon? ”

Compared with the little Taoist priest before, Li Tai must be more concerned about Yuan Tiangang's words, coupled with Yuan Tiangang's flickering, which made him feel that if he only lifted the hot air balloon into the air so plainly, it was really not interesting, and it would be better to call more people, so he agreed to Yuan Tiangang's suggestion.

Yuan Tiangang, who breathed softly, cast a grateful look at Jia Yi, and then bowed to everyone and then retreated directly, staying here for a second longer would be a great torment for him, God knows if there is anything else that His Royal Highness the King of Wei has not said.

Now that the time is set, everyone has no idea of staying here, Jia Yi asked people to put the hot air balloon into the house after it was put away, and then went directly back to his room.

The foreshadowing from above the court made Jia Yi feel a little uneasy, although he knew that even if Li Er was angry with him, he would not lose his head, but Jia Yi didn't know where Li Er would send him to, and as for the idea of being lucky not to be held accountable by Li Er, Jia Yi didn't even think about it.

On the one hand, Jia Yi did an experiment and injured Li Tai, which made Li Er feel very distressed, and then although Jia Yi taught Li Tai a lot of things, but this drama really has no great effect in the eyes of ordinary people, even if it is a hot ball, it can be used to fight a war or can be used to govern the country, obviously it can't, so no matter whether it is Li Er or the ministers of the court, they all directly regard this hot air balloon as a toy that Jia Yi uses to lead the big guy to play, and the name of a loafer who is idle and does not do his job has long been quietly hung on Jia Yi's head.

With the temper of the big guy, I believe that Jia Yi's departure can make the big guy feel a little relieved.

"Husband, His Royal Highness the Crown Prince is here." Lin Ruyu didn't know when she appeared behind Jia Yi, who was full of sadness, and stretched out a pair of Qianqianyu hands and gently kneaded Jia Yi's shoulders, which explained the intention.

"Oh, I'll go over here." There is nothing to hide the sorrow on Jia's face, even in the face of Lin Ruyu, there is no cover-up, the next turmoil belongs to the entire Jia family, although Jia Er will not be implicated because of his fault, but the three daughters-in-law who are directly related to Jia Yi will inevitably follow him to a new location, so there is no need to hide it at all.

"His Royal Highness the Prince." Jia Yi still came to Li Chengqian's face with a sad face, and saluted slightly.

"Jia Yi, I know that everything you have done for me during this period of time is for me, but I came here today to tell you bad news, and I hope you can have a mental preparation."

"The prince is serious."

Why did Jia Yi put a lot of gentlemen and Li Taila by his side to do these things, no one knows better than Li Chengqian, from the perspective of Li Chengqian's stable rights and scope of responsibility during this time, he is definitely the biggest beneficiary during this time, but unfortunately Jia Yi did things very hidden, but he still couldn't escape the eyes of many old foxes, and retribution will always come.

"The ministers are all admonishing, I hope that my father can send you to the Yangtze River Delta."

This decision made Jia Yi slightly stunned, if it was changed to Longyou Lingnan or something, Jia Yi might be able to worry a little, after all, these two places are not a good place to be rich, and it is unlikely that there will be much development in a short period of time, but I didn't expect the ministers to want him to go to the Yangtze River Delta, where is this still a distribution, it is simply a gift.

In an instant, the sadness on Jia's face suddenly dissipated, and at the same time, he also figured it out, which must have been promoted by people such as Qin Qiong, Fang Xuanling and others, Jia Yi was grateful to them and found a good relationship that had gone down before, and it really worked at a critical moment.

Seeing the sadness on Jia's face, although Li Chengqian was a little puzzled, he also knew that this Yangtze River Delta must be the place where Jia Yi wanted to go, and seeing that his friend did not have any unpleasant expressions because of being degraded, he was also happy for Jia Yi from the bottom of his heart.

Jia Yi looked at Li Chengqian, who also had a faint smile on his face, and suddenly thought of the fierce light flashing in Li Chengqian's eyes that he saw in the court today, and hurriedly reminded him.

"Cheng Qian, you are the crown prince of the Tang Dynasty, and the eldest brother of the kings, throw away the throne, you still have the same blood in your body, you have no shortage of ruthlessness, if you can add some tenderness to your body, I believe your position will become more stable."
